If you’ve ever wondered how many trees are cut down every year, the shockingly short answer is that more than 15 billion trees are lost annually to deforestation.5
While that number is staggering, it can be hard to visualize.
This image makes it a little easier to grasp…
For the 15 billion trees that are chopped down each year, every person on the planet could have 3,000 rolls of toilet paper.
If you imagine 3,000 rolls of toilet paper sitting in your bathroom, they likely wouldn’t all fit. Now imagine how many trees just those 3,000 rolls equate to, and the amount of deforestation it represents.
Without those trees, many endangered animals become more vulnerable and others are forced to find new homes. Plus, the atmosphere is stuck with higher levels of greenhouse gases that would have otherwise been stored by those trees (as a carbon sink). Sadly, many people are unaware of both the causes of deforestation and the impact it is having on our planet.
And if people don’t know about it, how can we stop it?
Why Do People Cut Down Trees? (Hint: It’s Not Paper)
There are a variety of reasons why people cut down so many trees… but here’s a spoiler – paper production is not one of the major causes. Sure, some things like toilet paper and paper goods (plates, paper towels, and paper itself) create a heavy toll on our worldly woodlands, but there are other, far more damaging actions that are destroying the Earth’s forests.
How Many Acres of Trees Are Cut Down Each Year?
As of 2020, the UN estimates the planet is losing over 7,000,000 hectares per year to deforestation.27 Between 1990 and 2015, the world lost 129 million hectares of forest – an area about the size of South Africa.11
Natural forests lost by continent9 include:
- Africa – 3.2 million hectares
- Asia – 1.1 million hectares
- Oceania – 200,000 hectares
- Europe – Due to excellent forest management, Europe did not net a loss of natural forestland in 2015 (the 2020 report has not yet been released)
- North America – 780,000 hectares
- South America – 3.6 million hectares
What’s the Definition of Deforestation?
The UN defines deforestation as “the direct human-induced conversion of forested land to non-forested land” or “the conversion of forest to another land use or the long-term reduction of the tree canopy cover below the minimum 10 percent threshold.”11
In plain English, it’s when people cut down or remove forests for whatever reason.
What Are the Five Main Causes of Deforestation?
There are specific causes that spur the destruction of forests, and when combined, the damaging impact on the planet is multiplied. Making matters worse, deforestation destroys natural carbon sinks which help to fight against growing greenhouse gas emissions and carbon footprint calculators along with reports from official governing bodies like the United Nations show that emissions are on the rise.
The following causes are the top five drivers of deforestation and account for the majority of forest cover loss.
Deforestation Cause #1: Farming
Of course, many people understand that food production is essential, they also argue that there must be ways of balancing the need for thriving forests along with meeting the nutritional needs of people around the world. And, we agree.
Deforestation Cause #2: Grazing and Feeding Livestock
A lot of deforestation is caused by the need for farmland, much of which is used to grow soy. Over 67% of soy is fed to animals, primarily poultry and pigs.35
Soy, palm oil, and cattle ranching are the most significant contributors to agricultural deforestation.31
Deforestation Cause #3: Drilling
Mining and drilling account for about 7% of all deforestation.32
Even when mining doesn’t directly lead to deforestation, the process of extracting resources from the earth often leads to large amounts of pollution. Unfortunately, some studies have shown that over 25% of metal mines worldwide can be found within 10km of a protected area.
For example, 15% of the Amazon is covered by active or planned oil concessions and 8% is covered by mineral concessions.32 This is why 8 Billion Trees is working so hard to fight to rebuild these areas that have been cleared (or are scheduled for clearing).
Deforestation Cause #4: Mining
Mining suffers from the same issues as drilling – it causes deforestation both through the direct clearing of forests and through pollution and industrial accidents.
It can also be prone to ecological disasters such as the infamous 2019 iron mining disaster in Brumadinho, Brazil. There are about 400 iron mines of the same type in the Brazilian state of Minas Gerais, and the Brumadinho disaster occurred just three years after a similar disaster just 75 miles (120km) away.15
Some of these issues could be solved with improved safety and environmental measures, but establishing a unified set of goals and restrictions throughout the world is highly problematic, given that not all nations would follow them.
Therefore, finding ways to work with individual governments is the key. By making an effort to stop ecological destruction, one region at a time, humans can actually do something about the problem, instead of waiting around and just talking about potential solutions.
Deforestation Cause #5: Wildfires
Wildfires are the cause of nearly one-quarter of all deforestation,25 including about half in North America.25 According to the US government, 2.2 million hectares burned this year in California alone with another 800,000 hectares destroyed in the northwestern U.S. – and many of those fires are still burning as of this publication.18 In fact, according to the UN,19 arctic fires in June and July of 2019 released a total of 129 megatons of CO2 resulting in a cloud of soot larger than the European Union.
Needless to say, this form of deforestation has Global Warming implications. The fires that ravaged Australia over the past two years have led to serious and dangerous ecological threats.
Other Reasons for Cutting Trees Down
In addition to the five main causes of deforestation, there are other, lesser-known reasons that so many trees are cut down.
Palm oil is the highest-yield, least expensive form of vegetable oil.29 Because its range is limited to the tropics, much of its market popularity has come at the expense of tropical rainforests. In fact, 90% of palm oil is produced in Malaysia and Indonesia,33 yet these are the only ecosystems that support the orangutan. Only about 2% of global palm oil production is considered sustainable. Palm oil is also used to produce biodiesel.31
Urbanization, complete with sprawling and booming populations, is another indirect cause of deforestation. While not a major cause of deforestation, urbanization is noteworthy for several reasons. First, roads and urban development can fragment forests so that they’re no longer continuous. While this may seem harmless at a glance, fragmentation and edge effects can have a devastating impact on wildlife.16 With a growing population, cities must expand, so more land is being used for agriculture and livestock to feed those people, and trees are being cut down to make room for it all.
Paper production is one of the more well-known other reasons for deforestation. If you’re wondering, a tree produces about 8,333 sheets of paper.20 A whopping 626,000 tons of paper are used to produce books each year in the US alone.
An average textbook contains about 700 pages, and about 30,000,000 trees are cut down to produce textbooks.20 Fortunately, there are a number of ways to reduce the number of textbooks needed, and many schools are embracing and opting for virtual books to counteract this amount.
The Link between Deforestation and Climate Change
Many people wonder why deforestation is linked to climate change.
The most obvious reason is that according to the US government, deforestation directly contributes to about 12% of all greenhouse gas emissions.24 Mature trees store carbon in their branches, trunks, leaves, roots, etcetera, and the forests themselves stores large amounts of carbon in their soil, which reduce and remove carbon emissions from the atmosphere.
After deforestation, much of this carbon is released in the form of CO2, a greenhouse gas. Slowing deforestation is viewed as a cost-efficient means of reducing overall greenhouse gas emissions.24
In fact, the UN environmental, developmental, and agricultural chiefs issued a joint statement saying that “Forests are a major, requisite front of action in the global fight against catastrophic climate change – thanks to their unparalleled capacity to absorb and store carbon. Forests capture carbon dioxide at a rate equivalent to about one-third the amount released annually by burning fossil fuels. Stopping deforestation and restoring damaged forests, therefore, could provide up to 30 percent of the climate solution.”
They further noted that “2020 will mark a pivotal moment in humanity’s quest for a sustainable future, when greenhouse gas emissions need to start declining if we are to avoid the most severe impacts of climate change.”6
The number of how many trees are cut down each year is so staggering, that if they were stacked on top of each other and just 3m (10 ft) tall, they’d reach the moon and back almost six times!
So, why don’t more people know about this cause and effect?
There’s really no one answer to this question. About a third of Americans don’t even believe that Global Warming is real, so it should come as no surprise that they aren’t familiar with the details.3 People also tend to avoid conflict. Americans overestimate the percentage of their peers who don’t believe in climate change.3 The result is that they avoid what they believe to be a controversial topic; in essence, this erroneous belief shuts down communication.
Deforestation in the Amazon
When people think of deforestation, the first thing that often comes to mind is the Amazon. The Amazon Rainforest has been called the lungs of the world, and we have a duty to take care of it. At least 390 billion trees are located in the Amazon.8,23 For perspective, that’s a forest roughly the size of the continental US.34 There are about 2.7 trillion trees in the world, so the Amazon contains about 14% of the world’s trees.5
Which Trees Sequester the Most Carbon?
The shihuahuaco tree sequesters the most carbon of any tree in the Amazon.2 It takes at least 1,000 years for a shihuahuaco tree to grow to its maximum height of 40m (130 ft), but a mature shihuahuaco can sequester 40 tons of carbon. In fact, each shihuahuaco sequesters about as much carbon as 1/3 of a hectare in the Amazon.1
Likewise, Mangroves are particularly good at sequestering carbon because their root system is particularly designed to store CO2.
Why Biodiversity Is Crucial to Survival
The World Health Organization has concluded that biodiversity is critical for sustaining the ecosystems that we rely on for our nutritional needs.30 It has also noted that along with the loss of biodiversity, we are losing many critical genes and chemicals before scientists get a chance to study them.
Understanding Rainforest Deforestation And Its Current Impact
Keeping the planets’ trees healthy and populous is not only good for the climate, it’s good for all of our existence. Trees are one of nature’s powerful ‘carbon sinks,’ areas that sequester and remove carbon dioxide from the atmosphere.
Since we’re making more and more CO2 every day, and simultaneously removing the planet’s method to deal with it… the equation is hugely imbalanced.
Rainforests and Jungles (Philippines Rainforest and More)
Although only about 7% of the world is covered with tropical rainforests, their ecosystems contain about half of the world’s species.14 Further, tropical rainforests store more carbon than other types of forests.14
It’s difficult to find up-to-date statistics for Philippine deforestation due to funding issues, but from 2003-2010, the Philippines lost nearly 1% (50,000 hectares) of its forests per year.9 This is particularly distressing as the Philippines is considered to be a biodiversity hotspot.28
Deforestation in America And Deforestation Rates
From the moment the first colonists set foot in America, deforestation began. It hasn’t stopped. In the US, deforestation rates are at about 385,000 hectares per year, but that’s not the entire story.
The US contains about 8% of the world’s forests; nearly 1/3 of the country is forestland or about 304 million hectares.26 Just over half belongs to the government; the rest belongs to private entities.
Despite losing about 385,000 hectares per year and harvesting nearly 4,000,000 hectares of timber each year between 1990 and 2010, reforestation efforts led to a net gain of over 7,500,000 over that period – or about 375,000 hectares per year.4
As mentioned previously, 2020 was a record-breaking year for wildfires, and not in a good way. Climate change is forcing America to reevaluate forest management, and unless action is taken soon, years like 2020 could one day become the norm.
Effects of Deforestation and the Dangerous Impact of Deforestation
We’ve already mentioned the fact that deforestation is actually making pandemics happen, but the additional loss of biodiversity and associated consequences aren’t actually the scariest thing about deforestation. Forests can actually have profound impacts on the weather. The rainforests of South America, for example, don’t just impact weather in South America – there’s evidence to suggest that they actually impact the global water cycle.17Thirsty?
Deforestation affects ecosystems, nutrition, weather patterns, and even the climate.17 But, it also impacts wildlife by destroying habitats and ecosystems, and there are other results:
- Ecosystems—About 80% of the earth’s terrestrial animals live in forests. Deforestation is an existential threat to many of them.
- Human Welfare—About 250,000,000 people live in forests or savannas and depend on them for their well-being.
- Air Quality—Forests have an enormous effect on the quality of the air we breathe. They act like a filter that strips much of the pollution (and carbon dioxide) out of the atmosphere.
- Global Warming—Forests act as carbon sinks, absorbing large amounts of CO2 (a greenhouse gas) from the atmosphere and storing it in the form of trunks, branches, leaves, etc. Deforestation destroys the trees; this both releases the carbon they’ve stored and prevents them from storing more
- Carbon – a double whammy. According to the World Resources Institute, if tropical deforestation (tropical alone!) were a country, it would rate third in CO2 equivalent emissions behind the US and China.13
- Water—Forests have a large impact on the water cycle and are critical for sustaining the water supplies of many nations such as Brazil due to their impact on the weather.
Finding Solutions to Deforestation
This problem is huge! But, there are ways to combat it.
Imagine what would happen if a farmer harvests his crops, but never planted new ones! It doesn’t take a genius to figure out that things won’t end well, but that’s exactly what’s happening with our forests in much of the world.
In fact, we’ve lost 46% of the forests that existed at the dawn of human civilization.5 Forest management isn’t just our moral obligation to the planet – it’s common sense.
Speak out. Make a difference. Make your voice heard. The US and Europe have stabilized their net rates of deforestation and have actually begun gaining trees in recent years. These sustainable models could work elsewhere, but only if we all work together.
Support Tree Planting Groups
You have the power to make a big difference in controlling and eliminating the impacts of deforestation. Many groups around the world are working to plant trees every day, and a small effort on the part of everyone could turn the tide and reduce the number of trees cut down every minute, every day, and every year.
